Hello friends,
I found another calyx ....or coral.
This one was deep in a split and was not exposed like the others. I lightly brushed the residue away. I left it like this for the pic to maybe aid with ID.
I think it would look much like the others if it were cleaned up.
If any other views, or exposure would help, just let me know.
Its 1.5 inches diameter.
Thanks !
